Professional oral care vs Usual oral care

Incidence of NHAP · Residents of nursing homes and other long-term care facilities
1 finding from 1 review
  • Incidence of NHAP, follow-up 8-30 months, 5018 (5 studies), Low. Not pooled (individual and cluster-randomised designs, varying effect measures and follow-up). Component estimates: Bourigault HR 0.65 (0.29 to 1.46;…

Cleft lip and/or palate (CL/P) vs No cleft lip and/or palate (non-CL/P)

Care index (CI = f/[d+m+f]) in the primary dentition · Children in the primary dentition with non-syndromic cleft lip and/or palate (CL/P) and comparable children without CL/P

The care index tended to be higher in children without CL/P (2 of 3 studies), suggesting more extraction-based caries management in children with CL/P; not pooled (narrative; ungraded).

  • Caries in children with and without orofacial clefting: A systematic review and meta-analysis. 2022 All outcomes
    Children with CL/P and comparable non-CL/P children across 12 countries (India, Brazil, China, Sweden, UK, USA, Germany, Greece, Ireland, Netherlands, Jordan, Thailand); studies published 1989-2021
    Two out of three studies for which the CI could be calculated (Nagappan 2019; Veiga 2016) showed a higher CI for non-CL/P children demonstrating a higher proportion of extraction-based treatment in CL/P children…

Concentrated growth factor (CGF) and primary wound closure vs primary closure

Healing of MRONJ (soft tissue healing) · Women with osteoporosis and established MRONJ

It is very uncertain whether concentrated growth factor (CGF) and primary wound closure changes healing of MRONJ (soft tissue healing) compared with primary wound closure only (very low certainty).

Professional oral care vs Usual oral care

Mortality (all‐cause) · Residents of nursing homes and other long-term care facilities
1 finding from 1 review
  • All-cause mortality, follow-up 12-30 months, 3764 (3 studies), Very low. Not pooled. Adachi RR 0.80 (0.40 to 1.58; 88); Juthani-Mehta HR 1.16 (0.88 to 1.53; 834); Zimmerman adjusted IRR 0.83 (0.61 to 1.12; 1606).…

Fluorescence-based devices vs Reference standard (histology, excavation, or enhanced visual examination)

Sensitivity for detection of enamel caries · Asymptomatic children or adults suspected of enamel caries (clinical studies); extracted teeth (in vitro studies)

Fluorescence-based devices had a summary sensitivity of 0.76 (95% CrI 0.68, 0.82) for detecting enamel caries; low certainty.

Antiretroviral therapy (any, including cART) vs No antiretroviral medication (treatment-naive)

Parotid hypertrophy prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

Parotid hypertrophy was significantly more prevalent in treatment-naive CLWH than in those on ART (very low certainty).

Baby-led weaning (BLW) vs Traditional complementary feeding (TCF)

Overweight/obesity risk · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

Among observational studies, baby-led weaning was associated with lower odds of overweight/obesity than other feeding models (OR 0.37, 95% CI 0.25 to 0.55), but certainty is very low.

Hypnosis vs relaxation

Adverse events · People aged 12 years and over with painful TMD lasting 3 months or longer

Good brushing habits (>=2 daily tooth brushing) vs Children without dental caries

Dental caries · Children (deciduous and/or permanent dentition) in low- and middle-income countries

Good brushing habits (>=2 daily) were associated with 35% lower odds of dental caries (OR 0.65, 95% CI 0.46 to 0.92; 7 studies; not GRADE-rated).

Traditional screening (referral card given if the inspecting dentist judges the child needs to see a dentist) vs No screening

  • School dental screening programmes for oral health 2022 · Cochrane All outcomes
    3 to 4 months
    Data not pooled; 6281 participants (4 RCTs); Very low. There was substantial heterogeneity, in part due to study design (3 cluster-RCTs and 1 individually randomised trial). We are unable to draw conclusions about this…

Single-surface ART restoration using high-viscosity glass ionomer vs Multi-surface ART with high-viscosity GIC

Restoration failure · Children (2-9 years) with caries in posterior primary teeth

Single-surface ART restorations had a low reported mean annual failure rate (about 5%; ungraded).
